PQPS: Prior-Art Query-Based Patent Summarizer Using RBM and Bi-LSTM

A prior-art search on patents ascertains the patentability constraints of the invention through an organized review of prior-art document sources. This search technique poses challenges because of the inherent vocabulary mismatch problem. Manual processing of every retrieved relevant patent in its entirety is a tedious and time-consuming job that demands automated patent summarization for ease of access. This paper employs deep learning models for summarization as they take advantage of the massive dataset present in the patents to improve the summary coherence. This work presents a novel approach of patent summarization named PQPS: prior-art query-based patent summarizer using restricted Boltzmann machine (RBM) and bidirectional long short-term memory (Bi-LSTM) models. The PQPS also addresses the vocabulary mismatch problem through query expansion with knowledge bases such as domain ontology and WordNet. It further enhances the retrieval rate through topic modeling and bibliographic coupling of citations. The experiments analyze various interlinked smart device patent sample sets. The proposed PQPS demonstrates that retrievability increases both in extractive and abstractive summaries.

Effects of Family Conflict and Social Support on Intention to Stay of Expatriates in Medical Technology Industry

Expatriates, during expatriation, would appear inadaptable feelings on work, life, and diet in different environment. Besides, expatriates, in medical technology industry, leaving home might neglect the family to result in imbalance between work and family. In this case, work-family conflict reveals the importance on expatriates. Expatriates in medical technology industry would appear psychosocial stress and conflict between work and life due to expatriation. Taking expatriates’ supervisors and expatriates in medical technology industry in southern Taiwan as the research object, total 360 copies of questionnaire are distributed, and the 278 valid copies are retrieved, with the retrieval rate 77%. The research results show that social support presents negative and significant effects on work-family conflict, work-family conflict reveals negative and remarkable effects on intention to stay, and social support appears positive effects on intention to stay. According to the results to propose suggestions, it is expected to provide healthy workplace in medical technology industry to improve expatriates’ work-family conflict and turnover.

Employment Profile and Program Relevance: Bases for Quality Measures Towards Language Curriculum

This research involved a comprehensive review of a graduate program’s competence for enhancements responsive and relevant to the standards of the new educational landscape and of the employment agencies’ growing needs and demands. Descriptive survey method embedding interview was used to address the objectives. Employing total enumeration, 70% retrieval rate of the instrument administered was recorded. Statistical and thematic analyses revealed that the MA- ESL degree, as similarly concluded, is contributory to the professional advancement of the graduates as supported by the high employment rating obtained consistent with the graduates’ regular status in professional occupational classifications and business lines. Significantly, the school- related factors were generally found very relevant- giving premium to curriculum, goals and objectives, and faculty and instruction. The work- related values on the other hand were rated highly useful- assessing perseverance and hard work of utmost importance. Of the general competencies, communication, knowledge and technical, and research were primarily found useful. Meanwhile, the feedback derived from the graduates, crosschecked with the above results, provided quality and timely enhancement measures. It is then forwarded that the proposed plan highlighting specific measures in the areas of curriculum and faculty and instruction may be adopted and accorded periodic evaluation.

Analysis of combined approaches of CBIR systems by clustering at varying precision levels

<span lang="EN-US">The image retrieving system is used to retrieve images from the image database. Two types of Image retrieval techniques are commonly used: content-based and text-based techniques. One of the well-known image retrieval techniques that extract the images in an unsupervised way, known as the cluster-based image retrieval technique. In this cluster-based image retrieval, all visual features of an image are combined to find a better retrieval rate and precisions. The objectives of the study were to develop a new model by combining the three traits i.e., color, shape, and texture of an image. The color-shape and color-texture models were compared to a threshold value with various precision levels. A union was formed of a newly developed model with a color-shape, and color-texture model to find the retrieval rate in terms of precisions of the image retrieval system. The results were experimented on on the COREL standard database and it was found that the union of three models gives better results than the image retrieval from the individual models. The newly developed model and the union of the given models also gives better results than the existing system named cluster-based retrieval of images by unsupervised learning (CLUE).</span>

The Evolving Role of Radiofrequency Guided Localisation in Breast Surgery: A Systematic Review

Wire-guided localisation (WGL) has been the gold-standard for localising non-palpable breast lesions before excision. Due to its drawbacks, various wireless alternatives have been developed, including LOCalizer™, which is based on radio-frequency identification (RFID) technology. In this systematic review, we consulted EMBASE, Medline and PubMed databases using appropriate search terms regarding the use of RFID technology in the localisation of occult breast lesions. Retrospective and prospective studies were included if they quoted the number of patients, rate of successful placement, retrieval rate, margin positivity rate and the re-excision rate. In addition, studies comparing RFID to WGL were also included and analysed separately. Seven studies were included in this systematic review spanning 1151 patients and 1344 tags. The pooled deployment rate was 99.1% and retrieval rate was 100%. Re-excision rate was 13.9%. One complication was identified. Two studies compared RFID with WGL (128 vs. 282 patients respectively). For both techniques the re-excision rate was 15.6% (20/128 vs. 44/282 respectively, p value is 0.995). Based on our review, LOCalizer™ is safe and non-inferior to WGL in terms of successful localisation and re-excision rates. However, further research is required to assess the cost effectiveness of this approach and its impact on the aesthetic outcome compared with WGL and other wire free technologies to better inform decision making in service planning and provision.

Comparison of Dydrogesterone and Medroxyprogesterone in the Progestin-Primed Ovarian Stimulation Protocol for Patients With Poor Ovarian Response

ObjectiveTo compare the clinical outcomes of dydrogesterone (DYG) and medroxyprogesterone (MPA) in the progestin-primed ovarian stimulation (PPOS) protocol for patients with poor ovarian response (POR).Patients and MethodsThis was a retrospective cohort study. Women with POR who underwent IVF/ICSI at the Reproductive Center of Third Affiliated Hospital of Zhengzhou University between January 2020 and January 2021 were included. The primary outcome measure of our study was the number of oocytes retrieved. The secondary outcome measures in the present study were the number of 2PN, number of available embryos, oocyte retrieval rate, fertilization rate, viable embryo rate per oocyte retrieved, cancellation rate and pregnancy outcomes of the first embryo transfer cycle, including the biochemical pregnancy, clinical pregnancy and miscarriage rates.ResultsIn total, 118 women underwent hMG +DYG protocols, and 692 women who underwent hMG +MPA met the Bologna criteria for POR. After baseline characteristics were balanced using the PSM model, 118 hMG +DYG protocols were matched to 118 hMG +MPA protocols, and the baseline characteristics were comparable between the two groups. The numbers of oocytes retrieved, 2PN, and available embryos and the oocyte retrieval rate, fertilization rate, viable embryo rate per oocyte retrieved and cancellation rate of the hMG+DYG and hMG+MPA protocols were comparable. Altogether, 66 women in the hMG+DYG group and 87 women in the hMG+MPA group underwent first embryo transfers. In the hMG+DYG group, 81.8% (54/66) of the patients underwent cleavage embryo transfers; similarly, 79.3% (69/87) of patients in the hMG+MPA group had cleavage embryo transfers (P=0.70).The biochemical pregnancy rate of the hMG+DYG group was 42.4%, and this was comparable to the rate in the hMG+DYG group, at 34.5% (P=0.32). The clinical pregnancy rates were similar between the two groups (36.4% vs. 31.0%, P=0.49), and there was no significant difference in the rate of miscarriage between the two groups (12.5% vs. 29.6%, P=0.14).ConclusionFor women with POR, the clinical outcome of the hMG + DYG group was similar to that of the hMG + MPA group, indicating that both combinations can be useful options for PPOS protocols.

Performing Microdissection Testicular Sperm Extraction: Surgical Pearls from a High-Volume Infertility Center

Microdissection testicular sperm extraction (mTESE) has been demonstrated to be the gold-standard surgical technique for retrieving testicular sperm in patients with non-obstructive azoospermia (NOA) as it enables the exploration of the whole testicular parenchyma at a high magnification, allowing the identification of the rare dilated seminipherous tubules that may contain sperm, usually surrounded by thinner or atrophic tubules. MTESE requires a skilled and experienced surgeon whose learning curve may greatly affect the sperm retrieval rate, as demonstrated in previous reports. The present review is intended to offer a precise and detailed description of the mTESE surgical procedure, accompanied by an extensive iconography, to provide urologists with valuable information to be translated into clinical practice. Advice about the pre-surgical and post-surgical management of patients is also offered.

Discussion of Students' E-book Reading Intention With the Integration of Theory of Planned Behavior and Technology Acceptance Model

The emergence of e-books with the characteristics of easy access and reading any time anywhere is a subject of debate in academia. Topics include the use of e-books in libraries, their use in support teaching, new possibilities for reading activities, potential uses for library archives, and the motivation and intention of e-book users. Students at Guilin University of Technology participated in a survey. Of the 300 copies of the questionnaire distributed, 263 valid copies were returned, a retrieval rate of 88%. The research results show that (1) Usability and reading need are the key factors in e-book usage. Usability refers to convenient keyword searches, portability, and any time reading. E-books are considered to make searching and reading large amounts of data easier. (2) E-books are not restricted to time and space so that the overall reading quantity is increasing. Readers become accustomed to reading e-books, and the quality of their digital reading is gradually enhanced. (3) Students should complete e-book use courses offered by libraries to enhance their familiarity with e-books and their use of e-book software, thereby enhancing postgraduate student readers' e-book information literacy. The results of the research prompt suggestions to enhance the promotion of reading and e-book information to encourage student readers' e-book reading intention.

Study on the Correlations among Environmental Protective Factor of Resilience, Social Exclusion, and Hope of Disadvantaged Youths

A needy family is the underprivileged group in the society, in which children and youths growing in a needy family are the most underprivileged group, who have no choice and could not overcome it by themselves. Effects of poverty on children contain malnutrition or disorder, more chronic diseases, higher epidemic disease infection rate, high accident rate, low study preparation, low learning achievement, high social emotion and behavior problems, high risk of domestic violence, and bad parent-child relationship. Discussions about poverty are often related to social exclusion. Some people regard social exclusion as the division of poor people; social exclusion is not simply a result, but a dynamic process; social exclusion is not the result of inequality, but the behavior to separate people and group due to systems. Aiming at disadvantaged youths in southern Taiwan, random sampling is adopted to distribute 450 copies of questionnaire, and 348 valid copies are retrieved, with the retrieval rate 77%. The retrieved questionnaire data are analyzed with statistics software. The research results show significantly negative correlations between environmental protective factor of resilience and social exclusion, remarkably negative correlations between social exclusion and hope, and notably positive correlations between environmental protective factor of resilience and hope. According to the results to propose suggestions, it is expected to provide various environmental factors in the growing process of youths for reinforcing youths’ confidence and cultivate the resilience.

Novel Blood Clot Retriever for Ischemic Stroke

Stroke is the second leading cause of death in the world. Ischemic stroke, caused by the blockage of intracranial arteries, accounts for approximately 80% of strokes. Among this proportion, acute ischemic stroke, usually caused by the sudden formation of blood clots, can cause fatal blockages in arteries. We proposed a unique blood clot retriever for the treatment of acute ischemic stroke, and conducted a series of tasks, including design, computer simulation, prototyping, and bench testing, for the proof of concept. Unlike most blood clot retrievers used today, our novel design deviates from traditional stent-like blood clot retrievers and uses large closed cells, irregular spikes, and strut protrusions to achieve maximum entanglement for better retrieval performance. Experimental results showed that the retrieval rate of our blood clot retriever was 79%, which demonstrated the feasibility of our new design concept.
